Rape is also called Shanghai green, Chinese cabbage, green vegetables, gourd ladle and so on. There is almost no need to change the knife for small cooking, and the smallest "chicken hair dish" is rape seedlings. As a representative component of green leafy vegetables, common rape has a nutritional value beyond imagination.

Strictly speaking, celery is not a green leafy vegetable, but mainly a tender stem. Many people are used to throwing away the leaves when eating celery. In fact, it is a pity, because the nutritional value of celery leaves is higher than that of celery stems. Due to the high sodium content, celery stems have a natural light salty taste. The salt content of celery stalk is about 0.4g per 100g. Therefore, when burning celery, you should put less salt and avoid taking too much sodium.
Spinach is also one of the most nutritious leafy vegetables. But spinach contains more oxalic acid. Oxalic acid can inhibit intestinal absorption of minerals such as calcium and iron, and increase the risk of kidney calculi after entering the blood. However, oxalic acid is easily soluble in water, so it should be blanched before making spinach to remove most of the oxalic acid. However, patients with kidney calculi's disease should limit their intake of spinach.

In addition to the nutrients often mentioned, Artemisia selengensis is worth mentioning its sodium content. Artemisia selengensis contains more sodium (161mg/100g), so it has a salty taste.
